摘　　要：在分析合环转电研究现状以及未来发展趋势的基础上,阐述地区电网合环转电的内涵和意义,归纳地区电网合环转电的基本类型主要为离线合环、在线合环和基于状态估计合环三种,并从地区电网外网等值和合环馈线电流计算两方面总结每种合环类型的基本计算方法,指出不同方法的适用条件,为进一步合环转电研究提供理论基础。On the basis of analyzing research status quo and future developing trend of switching power supply in closed loop, this paper states connotation and meaning of switching power supply in closed loop of regional power grid and summarizes basic types of it as off-line closed loop,on-line closed loop and closed loop based on state estimation. In aspects of external equivalence of regional power grid and closed loop feeder current calculation,it summarizes basic computing methods for each closed loop and points out different applicative conditions which may provide theoretical basis for further research on switching power supply in closed loop.
